By this, I meant that rather than have 9 nofollowed links & 1 normal link, there is just 1 normal link.

This would be 'the perfect' scuplting, and would give you an idea of the best possible result that could be acheived. Comparing the variance with other methods would be useful as well, to get an idea of how effective the other methods actually are.

Danny - "As expected the Javascript method did not work at all (Since the external scripts were blocked, the engines never saw the links) "

Sorry for the requote, but isn't the 'engines never seeing the links' exactly what we are hoping for with PR sculpting? Why were you expecting the javascript method to fail if you thought that the links would never be seen?

Great video. Just asking for a quick clarification between Comment Spam and DoFollow Blogs.

I realise comment spam is putting your keywords in the Name of your comment so that you get the link back (even if it is mostly nofollow).

Are *all* links from a dofollow blog counted as 'low quality'? (even editorial comments within a post). Or is this just referring to the dofollow link you get back to your site when you post a comment?
